As part of my seemigly endless home remodeling, SWMBO has asked if I could lay a hardwood floor on our stair treads to match the floor in the entrance hall

We have a spiral staircase, doubling back 180 degrees from top to bottom. This is not a problem initself (few more angles to consider and cut) but the treads are MDF with a bullnose front edge protruding over the riser by about 3/4”. The floor planks are 3” x 3/4”

Does anyone know how I would have to approach this job? do I rout off the bullnose flush with the riser and then edge band the routed edge (not my first choice bearing in mind the dust produced by this method)...... or do I have to double up and glue two flooring planks to create an inch and a half blank/plank then rout a cove on the back edge to cap over the bullnose on the tread?

I have seen what looks like a cap peice in an office building staircase but decided not to get down on my hands and knees to investigate further at the time.

Do flooring manufacturers generally provide a cap peice for this purpose? just haven’t come across them at all

Just one of those jobs where I can’t see the wood for the trees (pun intended)

Application of 3/4” flooring over the treads will change the riser height on the bottom and top tread. The bottom step will be 3/4” higher than the rest and the top will be 3/4” lower. Uneven stair risers are very dangerous and will lead to accidents. So the answer is no you can’t do this. Rip out the treads and do it right or don’t do it at all.

You heard him. What you propose is against code and will result in no insurance coverage in case of the inevitable accident. I ripped mine out, bought rough red oak 10/4 (that’s all they had), milled glued up and used a round over bit to profile the edge. Stained it a close match to the lr floor, and 3 coats of poly. If you’re gonna o it, do it riight.
